3. Karan S’jet-sa
While Karan S’jet (as she’s more popularly known) is not exactly an A.I. in the traditional sense of the term, she is in many ways the ultimate step in the evolution of humans and A.I. A merging of intellect. Karan S’jet of the Homeworld series is Sajuuk-Khar, the chosen one. A creature that brings peace to the galaxy, the Age of S’jet.
4. HALMAN (HAL 9000)
An A.I. that has transformed from murderer to martyr to saviour of the human race, one that finally merged with an ancient, but ridiculously advanced alien artifact and the “soul” of a dead spaceman. Such an A.I. has been through a lot and for it to sacrifice itself a second time to save the human race indicates a very noble nature indeed.
5. Deep Thought
If the other A.I.s here have saved the human race, Deep Thought is the A.I. that’s been responsible for the creation of the human race. Designed to find the answer to the “Ultimate question of life, the universe and everything”. It finds the answer (42), but it doesn’t know the question. The Earth is a result of the quest to find that very question.
Mass Effect is considered by many to be one of the best trilogies in gaming history and while Shepard may be the hero, EDI is the side-kick that provided the support that kept that said hero alive. A sentient shipboard A.I. that finally acquires a physical form, EDI has saved the known (game) universe many times with her hacking (and combat) skills.
